[摘 要]目的 探究口腔正畸结合修复治疗在错颌畸形伴第一磨牙缺失患者中的应用效果。方法 选取2021年1月-2023年1月于本院进行治疗的90例错颌畸形伴第一磨牙缺失患者作为研究对象，根据治疗方法不同分为对照组和试验组，各45例。对照组给予传统牙齿修复治疗，试验组给予口腔正畸结合修复治疗，比较两组咀嚼功能、牙周健康指标、口腔修复效果及不良反应发生情况。结果 两组治疗后咀嚼效率、咬力值均高于治疗前，且试验组高于对照组(P<0.05)；两组治疗后牙龈指数(GI)、出血指数(BI)、探诊深度(PD)均降低，且试验组低于对照组(P<0.05)；试验组口腔修复优良率为95.56%，高于对照组的77.78%(P<0.05)；两组不良反应发生率比较，差异无统计学意义(P>0.05)。结论 错颌畸形伴第一磨牙缺失患者采用口腔正畸结合修复治疗，能够提高咀嚼效率、咬力值，改善牙周健康指标，降低不良反应发生率，提升口腔修复优良率，值得临床应用。
